Lehigh ISE Faculty Member to Chair the Bilevel Optimization Society

Lehigh ISE Professor Ted Ralphs has been elected Chair-Elect of the Bilevel Optimization Society (BOS). He will serve a one-year term as Chair-Elect before assuming a two-year term as Chair, followed by one year as Past Chair. Bilevel optimization is a field of optimization that addresses hierarchical optimization problems in which a leader (upper level) decides the values of a set of decision variables and a follower (lower level) reacts by solving a problem that depends on the leader’s choice.

National defense program selects Lehigh Engineering professor Keith Moored

Keith Moored, a professor of mechanical engineering and mechanics in Lehigh University’s P.C. Rossin College of Engineering and Applied Science, was recently selected to join the Defense Science Study Group (DSSG), a highly selective program that connects leading academic researchers with U.S. national security challenges. Moored is one of just 18 academics selected from more than 150 nominated by universities across the country for the class of 2027-28.

Javad Khazaei earns NSF CAREER Award to streamline smart grid control

The modern power grid is no longer a straightforward, one-way system. 

Just 20 years ago, demand strictly dictated generation. Today, the grid is a massive, nonlinear web driven by distributed energy resources (DERs), such as solar arrays, wind farms, and battery storage. These resources rely on power electronics to interface with the grid, creating bidirectional flows where customers (including communities and even individual households) can both consume and supply electricity.

Rethinking newborn screening for critical congenital heart disease

Critical congenital heart diseases, or CCHDs, are a group of life-threatening structural heart defects present at birth. According to the Centers for Disease Control and Prevention, about 1 in 4 babies born with a heart defect has a CCHD, and treatment—medication and/or surgery—must take place within the first year of life. 

Today, all babies born in U.S. hospitals are screened for these conditions using pulse oximetry, a noninvasive test that measures blood oxygen levels.
